XGrabKey(3)                     XLIB FUNCTIONS                     XGrabKey(3)

       XGrabKey, XUngrabKey - grab keyboard keys

       int XGrabKey(Display *display, int keycode, unsigned int modifiers,
              Window grab_window, Bool owner_events, int pointer_mode, int

       int XUngrabKey(Display *display, int keycode, unsigned int modifiers,
              Window grab_window);

       display   Specifies the connection to the X server.

                 Specifies the grab window.

                 Specifies further processing of keyboard events.  You can
                 pass GrabModeSync or GrabModeAsync.

       keycode   Specifies the KeyCode or AnyKey.

       modifiers Specifies the set of keymasks or AnyModifier.  The mask is
                 the bitwise inclusive OR of the valid keymask bits.

                 Specifies a Boolean value that indicates whether the keyboard
                 events are to be reported as usual.

                 Specifies further processing of pointer events.  You can pass
                 GrabModeSync or GrabModeAsync.

       The XGrabKey function establishes a passive grab on the keyboard.  In
       the future, the keyboard is actively grabbed (as for XGrabKeyboard),
       the last-keyboard-grab time is set to the time at which the key was
       pressed (as transmitted in the KeyPress event), and the KeyPress event
       is reported if all of the following conditions are true:

       o    The keyboard is not grabbed and the specified key (which can
            itself be a modifier key) is logically pressed when the specified
            modifier keys are logically down, and no other modifier keys are
            logically down.

       o    Either the grab_window is an ancestor of (or is) the focus window,
            or the grab_window is a descendant of the focus window and con-
            tains the pointer.

       o    A passive grab on the same key combination does not exist on any
            ancestor of grab_window.

       The interpretation of the remaining arguments is as for XGrabKeyboard.
       The active grab is terminated automatically when the logical state of
       the keyboard has the specified key released (independent of the logical
       state of the modifier keys), at which point a KeyRelease event is
       reported to the grabbing window.

       Note that the logical state of a device (as seen by client applica-
       tions) may lag the physical state if device event processing is frozen.

       A modifiers argument of AnyModifier is equivalent to issuing the
       request for all possible modifier combinations (including the combina-
       tion of no modifiers).  It is not required that all modifiers specified
       have currently assigned KeyCodes.  A keycode argument of AnyKey is
       equivalent to issuing the request for all possible KeyCodes.  Other-
       wise, the specified keycode must be in the range specified by min_key-
       code and max_keycode in the connection setup, or a BadValue error

       If some other client has issued a XGrabKey with the same key combina-
       tion on the same window, a BadAccess error results.  When using AnyMod-
       ifier or AnyKey, the request fails completely, and a BadAccess error
       results (no grabs are established) if there is a conflicting grab for
       any combination.

       XGrabKey can generate BadAccess, BadValue, and BadWindow errors.

       The XUngrabKey function releases the key combination on the specified
       window if it was grabbed by this client.  It has no effect on an active
       grab.  A modifiers of AnyModifier is equivalent to issuing the request
       for all possible modifier combinations (including the combination of no
       modifiers).  A keycode argument of AnyKey is equivalent to issuing the
       request for all possible key codes.

       XUngrabKey can generate BadValue and BadWindow error.

       BadAccess A client attempted to grab a key/button combination already
                 grabbed by another client.

       BadValue  Some numeric value falls outside the range of values accepted
                 by the request.  Unless a specific range is specified for an
                 argument, the full range defined by the argument's type is
                 accepted.  Any argument defined as a set of alternatives can
                 generate this error.

       BadWindow A value for a Window argument does not name a defined Window.
